Abstract

Oil and gas energy is one of the necessary energy sources for social development. In the process of oil development and exploration, hydraulic fracturing technology plays a vital role. Hydraulic fracturing technology can not only stabilize the production of conventional oil and gas fields, realize the development of low-permeability oil and gas reservoirs, help the development and adjustment of old oil fields, but also increase the development production of special oil reservoirs and tap the potential of oil and gas fields. In this paper, an electrical simulation experiment method for the productivity of horizontal well staged fracturing is studied. Firstly, according to the actual formation conditions after staged fracturing of horizontal wells, a set of three-dimensional electric field simulation device is simulated and developed; According to the wellbore trajectory, formation permeability and formation thickness, etc., the electrolyte and electrolytic cell size for electrical simulation are set. Finally, the current signal is collected to determine the size of the production capacity. Using this experimental method, we carried out the optimization simulation of horizontal well fracturing fracture shape and location, optimization simulation of fracture number and spacing, and comparison of different formation thicknesses for a fluvial facies sedimentary sand body. This electrical simulation experiment method can accurately simulate the influence of various parameters of horizontal well fracturing and completion on productivity, and has certain guiding significance for the design of horizontal well fracturing and completion.
